In a recent article by Daniel Peterson, he gives examples of prophets and apostles bearing testimony of the Savior since Joseph Smith saw God the Father and Jesus Christ in the Sacred Grove. Here is just one such testimony:

Elder Orson F. Whitney, a member of the Quorum of the Twelve Apostles between 1906 and 1931, had a life-changing experience while serving as a missionary in Pennsylvania:

“One night I dreamed — if dream it may be called — that I was in the Garden of Gethsemane, a witness of the Savior’s agony. I saw him as plainly as I see this congregation.” The vision continued, he said, until “I was perfectly familiar with his appearance — face, form and movements.”

“Then came the divine illumination, which is greater than all dreams, visions and other manifestations combined. By the light of God’s candle — the gift of the Holy Ghost — I saw what till then I had never seen, I learned what till then I had never known, I loved the Lord as I had never loved Him before. My soul was satisfied, my joy was full, for I had a testimony of the truth, and it has remained with me to this day. I know that my Redeemer liveth. Not even Job knew it better. I have evidence that I cannot doubt” (see “The Divinity of Jesus Christ,” Liahona, December 2003).
